Answer:

Step-by-step explanation:

Recognize that the correct answer depends upon the value of a, which is not given here.

               

                     1

If    f(x) = ------------ and x = 0 (which I have invented), then f(0) = 1 / (0² + 1) = 1

                 x² + 1

If x = 1/2, then f(1/2) = 1 / (1/4 + 1) = 4/5

and so on.  Ask your teacher, if possible, what value to use for a.
